Skylight

Abstract

In skylights wherein the wing may be selectively adjusted into a pivoting and swivel position, the wing is fixed with respect to the auxiliary frame in the pivoted opened position. If this fixation is removed due to a faulty operation, the upper, heavier half of the wing moves in the direction of the case so that there is a danger of damage. To make the negative effects of the faulty operation ineffective, flap 18 provided with latch 19 and having a pivoting axis displaced in relation to axial pin 7 in the direction of swivel joint 5 is pivotally mounted on auxiliary frame 2. Latch 19 arranged at a slight distance from axial pin 7 in the closed position subtends axial pin 7 when wing 3 is pivoted open. In case of a faulty operation, the weight of wing 3 causes axial pin 7 to be pressed against latch 19 of flap 18. This automatically secures a pivotally opened skylight against the results of a faulty operation, which is automatically undone, FIG. 4, when the wing is brought into the closed position.

I claim: 
     
       1. A skylight comprising (a) a case having lateral legs and an upper edge connecting the lateral legs, the lateral legs defining respective end faces,   (b) a wing having lateral struts adjacent the lateral legs of the case,   (c) an auxiliary frame supporting the wing on the case for pivoting between a closed and a swing position in relation to the end faces of the case,   (d) a swivel joint connecting the wing to the auxiliary frame,   (e) a hinged joint connecting the auxiliary frame to the upper edge of the case, the joints enabling the wing to be pivoted between the closed and swing positions,   (f) a locking device operative to position the wing in relation to the auxiliary frame and to lock the wing to the case in the closed position,   (g) pins fastened to, and projecting from, the lateral struts of the wing, the pins being arranged between the swivel and hinged joints, and the pins engaging the end faces of the lateral legs of the case in the closed position of the wing,   (h) flaps pivotally arranged on the auxiliary frame for engagement with, and disengagement from, the pins, and   (i) a respective pivot displaced in relation to a respective one of the pins in the direction of the swivel joint and permitting free pivoting of a respective one of the flaps about the pivot, (1) the flaps having a detent at a free end remote from the pivots and a run-up ramp positioned on a respective one of the end faces of the lateral case legs in the closed position of the wing whereby the detents are out of engagement with the pins in said position, and the flaps freely pivoting when the auxiliary frame and the pins fastened thereto are lifted off the end faces whereby the detents of the flaps are coupled to the pins to permit the wing and auxiliary frame to be pivoted in unison into the swing position.     
     
     
       2. The skylight of claim 1, wherein the locking device operative to position the wing in relation to the auxiliary frame and to lock the wing to the case in the closed position comprises a positioning linkage built into the wing, a latch housing affixed to the auxiliary frame for engagement by the linkage, and an operating handle on the wing for actuating the linkage to engage the latch housing for positioning the wing in relation to the auxiliary frame for permitting the wing and the auxiliary frame to be pivoted in unison, the coupling of the flap detents to the pins permitting the pivoting of the wing and the auxiliary frame in unison when the locking device fails. 
     
     
       3. The skylight of claim 1, wherein the flaps have an abutment face remote from the free ends thereof for engagement with the auxiliary frame. 
     
     
       4. The skylight of claim 1, wherein the pivots for the flaps are bolts fastened to the auxiliary frame and the flaps are freely movably mounted on the bolts. 
     
     
       5. The skylight of claim 1, wherein the flaps are of synthetic resin.
